Trapped with a Vengeance is the second segment of the thirty-sixth episode in season 2 of Dexter's Laboratory. It first aired on April 22, 1998.

In this episode, Yani, the janitor at Huber Elementary gets fed up with Dexter making messes in the school's science lab, forcing him to stay overnight and clean up Dexter's messes. He plots to get revenge on Dexter by preventing him from going home.


Yani, a janitor at Huber Elementary, gets fed up with having to clean up Dexter's messes, which cause him to stay at his job overnight to clean up. One day, Dexter decides to stay behind in the science lab to finish working on his invention. As he gets a message from Computer about Dee Dee destroying his lab, Dexter immediately plans on getting home as soon as he can, prompting Yani to hatch his plan. He does so by closing every classroom door, barring the windows, and activating the security cameras. Back in the science lab, Dexter packs his things up and prepares to leave, but is unable to as Yani has locked the door. Dexter tells him he's about to leave for the night, but Yani objects.

Thinking of a way to escape, Dexter activates the fire alarm and attracts a group of firefighters. The chief demands Yani to open the school doors, but Yani tells him that the fire alarms going off was "a glitch in the system". Buying his excuse, the chief firefighter and the others leave. Catching on to Dexter's scheme, Yani returns to the security room to find that Dexter escaped through the school vent. To chase him out, Yani turns up the heat, forcing Dexter to crawl faster than usual. Dexter then finds himself in a channel of vents and climbs into one, but is blown out by a fan.

Dexter lands on top of an elevator that sends him up. He tries to stop the elevator, though his boots catch fire from the high amount of friction. As the elevator nears the top, it then goes back down. Dexter jumps into another vent and finds himself in the school hallway, giving Yani the upper hand. Dexter races through the hallway trying to escape, as many of his routes are blocked off by metal gates. He enters the cafeteria, where Yani meets him face to face. To taunt Dexter, Yani opens the door and orders him to go home. Instead of falling for his ploy, Dexter charges at him. Yani then attacks Dexter by throwing several ketchup packets at Dexter, then attacks him by throwing several sporks. Angered, Dexter walks toward the double doors, though they close just as he gets near them. Dexter then orders Yani to clean up the cafeteria, making Yani highly irate. He and Dexter brawl it out, with Yani's wife interrupting as she bursts the double doors open.

She then explains to Yani that she waits for him to come home every night, then accuses her husband of "goofing off" and orders him to come home. Dexter picks up Yani's key and opens the door. Yani, in absolute defeat, goes home with his wife while Dexter walks home whistling "Jingle Bells".

Cultural references[]

  • As Dexter walks home, he whistles the song "Jingle Bells."
  • Parts of this episode are a reference to the film Die Hard with a Vengeance. Dexter crawls through the vents inside the school similarly to the protagonist John McLane in the vents of Nakatomi Plaza. In the cafeteria, Dexter walks on several potato chips barefoot, similarly to how John McLane did with shattered glass.


  • It is illegal for Yani to keep Dexter trapped inside Huber Elementary and refuse to let him leave, as this is considered false imprisonment. In the real world, Yani would've faced jail time.
  • The double doors in the cafeteria open both ways. As such, when Yani's wife came in, the double doors flipped to the inside, but when she orders Dexter to open the doors, they flip to the outside.
  • Throughout the episode, Yani's mustache is simulated as a mouth, but in one shot when Dexter's alarm goes off, his mouth actually moves when he says "Sure, Dexter, no problem."
